Predicted to enable voltage-gated potassium channel activity. Predicted to be involved in potassium ion transmembrane transport and regulation of delayed rectifier potassium channel activity. Predicted to be located in perinuclear region of cytoplasm and plasma membrane. Predicted to be part of voltage-gated potassium channel complex. Predicted to be integral component of membrane. Orthologous to human KCNS2 (potassium voltage-gated channel modifier subfamily S member 2). [provided by Alliance of Genome Resources, Apr 2022]
